  2. Trouton's rule - Wikipedia

    en.wikipedia.org/wiki/Trouton's_rule

    In thermodynamics, Trouton's rule states that the (molar) entropy of vaporization has almost the same value, about 85–88 J/(K·mol), for various kinds of liquids at their boiling points. [1] The entropy of vaporization is defined as the ratio between the enthalpy of vaporization and the boiling temperature. It is named after Frederick Thomas ...

  3. Chemical potential - Wikipedia

    en.wikipedia.org/wiki/Chemical_potential

    In thermodynamics, the chemical potential of a species is the energy that can be absorbed or released due to a change of the particle number of the given species, e.g. in a chemical reaction or phase transition.

  4. Diffusion - Wikipedia

    It goes from regions of higher concentration to regions of lower concentration. Sometime later, various generalizations of Fick's laws were developed in the frame of thermodynamics and non-equilibrium thermodynamics. [4] From the atomistic point of view, diffusion is considered as a result of the random walk of the diffusing particles.

  5. Chemical warfare - Wikipedia

    en.wikipedia.org/wiki/Chemical_warfare

    Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. [1] [2] This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear (warfare or weapons), all of which are considered "weapons of mass destruction" (WMDs), a ...
